function
The compression of the programme signal takes place evenly over
the entire input level range and not only at the upper end above a
certain threshold level. Dynamic structures of the input signal (e.g.
dynamic evolutions) are converted proportionally so that even after
compression the ratios are maintained, only slightly condensed,
leaving on the whole a transparent, seemingly uncompressed sound
impression.

Compression (reduction of the dynamic range of the input signal to
match the dynamic range of the storage or of the transmission system)
is partly achieved by increasing the level of low level signals, the
lowest of which might otherwise be below the noise floor of the audio
system.
The lower the input signal level the higher the additional gain
applied to that input signal by the compression processing will be.
